Patented June 19, 1951 2,557,459 OF Fl CE APPARATUS FOR FEEDING RADIATOR VAPOR COMBINED WITH AN ANTI- CORROSION AND ALKALINE INHIBIT- ING SOLUTION INTO THE FUEL FEED LINE OF AN INTERNAL-COMBUSTION ENGINE Rudolph Oros, Los Angeles, Calif. Application September 6, 1949, Serial No. 114,234 8 Claims. (01. 123-25) This invention has for its primary object to provide a simply constructed apparatus, which as an attachment, may be readily installed on a water cooled internal combustion engine for feeding, into the fuel line thereof, vapor from the radiator combined with a solution for inhibiting corrosion, rust and alkaline deposits, whereby the vapor will improve the combustion of and conserve fuel, and the solution will prevent objectionable and damaging corrosion, rust and alkaline deposits which, due to the water vapor, might otherwise be caused within the cylinders and on the valves, valve seats and other working parts exposed to such vapor.

Another object is to provide apparatus of the character described in which the vapor feed line is installed so as to lead from the tank of the engine radiator, above the water line, to, the air intake conduit of the carburetor, for introducing vapor with the carbureted fuel into the engine cylinders, there being a reservoir for the anticorrosion and alkaline and rust inhibiting solution connected to said vapor feed line whereby the solution is fed with the vapor into the carburetor and thence into the engine.

Another object is to provide apparatus of the character described in which a single valve operable, for example, on the instrument panel of the automobile, is arranged to control the flow of the vapor-solution mixture into the air intake conduit of the carburetor.

Another object is to provide apparatus such as described in which a valved outlet is arranged to regulate the rate of flow of the alkaline and corrosion inhibiting solution into the vapor feed line leading to the air intake of the carburetor and wherein feed of such solution through said outlet is caused by vibration of the reservoir for such solution plus the suction effect in the vapor feed line.

A furthe object is to provide vapor feed apparatus such as described wherein the overflow drain pipe of the radiator is screened to prevent dust and other foreign matter from being sucked through said pipe into the radiator tank and thence in the vapor feed line leading to the carburetor.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawing, in which:

, Fig. 1 is a fragmentary elevational view of a liquid cooled internal combustion engine as'in an automobile showing an apparatus embodying my invention as installed thereon, and

Fig. 2 is a fragmentary sectional view taken on the line 2-2 of Fig. 1 showing the valved outlet forthe-reservoir for the solution for inhibiting corrosion and alkaline deposits and the manner of connecting the outlet with the vapor feed lines.

As shown in the accompanyingdrawing one embodiment of my invention includes the provision of a vapor feed tube or line 3 which is connected with tank 4 of the radiator 5 of a water cooled internal combustion engine 6, here shown as the engine of a motor vehicle having an 'instrument panel I. This line is connected with the top of the tank above the water line and leads downwardly to a point of connection 8 with the air intake conduit 9 of the carburetor ll] so that vapor rather than water is conducted to the carburetor and then with the carbureted fuel mixture through the intake manifold I l to the engine 6. The exclusion of water from the line 3 is further prevented by the goose neck formation l2 in the end of the line connected to the top of the tank' l.

As a means to prevent the suction created in the vapor feed line 3 from drawing dust and foreign matter into the overflow pipe l3 of the radiator and thence into the vapor feed line, the discharge end of the overflow pipe is covered with a suitable screen M.

It is now seen that in having vapor from the radiator fed into the carburetor as here provided and introduced as a carbureted fuel mixture into the engine, a better and more efiicient combustion takes place and a conservation offuel'is achieved.

As here provided a suitable valve I5 is mounted in the vapor feed line 3 for controlling the flow of vapor into the air intake conduit 9. This valve may as here shown be controlled from themstrument panel I by means of a suitable Bowden wire unit i6 whereby the driver of the vehicle may start and stop and regulate the flow of vapor at will.

In accordance with this invention, to prevent corrosion, rust and alkaline deposits in the engine due to the introduction of the radiator vapor, I provide for introducing into the'vapor feedline 3, a solution for inhibiting corrosion, rust andalkaline" deposits. To this end a reservoir I1 is mounted in any suitable manner over or on' the engine so that it may be connected with the vapor feed line 3 between the valve 1 5 and the radiator tank 4 for a gravitational discharge of the aforesaid solution into the feed line, with the valve l5 controlling the flow of the solution as well as the vapor. Accordingly the reservoir is connected to the line 3 by means of' a suitable fitting 18in which a needle valve I9 controls the flow through a passage 20, extending through the fitting and connecting the interior of the reservoir with the line 3. I

Any solution which will inhibit corrosion-rust and alkaline deposits maybe used and I have found that a solution of a liquid compound known as Malco 37 is well suited.

When the valve I5 is opened and the engine 6 in operation the suction in the fuel feed line of the engine is effective to draw vapor from the radiator tank through the vapor line 3 and through the carburetor I0 and manifold ll into the engine fo the purpose of improving combustion and conserving fuel.

At the same time the vapor is being fed to the engine, the solution in the reservoir I! (the needle valve I9 being opened) feed into the line 3 and is drawn with the vapor into the engine. The adjustment of the needle valve 19 determines the rate of flow of solution, it being noted that but a'small amount is required in mixture with the vapor to be effective to inhibit rust, corrosion and alkaline deposits. The vibration of the reservoir due to the operation of the engine plus the suction in line 3 induces a feed of the solution into the line 3.

I may use a small amount of a suitable lubricating oil in the aforesaid solution, for the purpose of lubricating the pistons, piston rings and associated parts of the engine.

One solution which I have found to be most effective consists of five gallons of water mixed with approximately two ounces of the rust and corrosion inhibiting compound and three ounces of a suitable cylinder oil. A small amount of this mixture placed in the reservoir I'I will suflice for the operation of the engine over a long period of time.

It will now be apparent that my apparatus as an attachment is readily applicable to water cooled internal combustion engines, will accomplish the objects and purposes hereinbefore stated in a particularly eflicacious manner.

While I have shown and described a specific embodiment of my invention, I do not limit myself to the exact details of construction set forth, and the invention embraces such changes, modifications and equivalents of the parts and their formation and arrangement as come within the purview of the appended claims.
